70%of it is 14 min find the valy ofx

Answers

Note:

Your questions sound a little unclear.

But, I am assuming your questions as:

''70% of x is 14 min. Find the value of x''.

So, I will solve assuming this statement which anyways would clear your concept.

Answer:

The value of x = 20.

Step-by-step explanation:

Given

''70% of x is 14 min. Find the value of x''.

Thus,

70% of x = 14

70/100 × x = 14

0.7x = 14

divide both sides by 0.7

0.7x/0.7 = 14/0.7

x = 20

Therefore, we conclude that the value of x = 20.

Answer:

The x-intercept is [tex]\frac{1}{8}[/tex]

The y-intercept is -1

Step-by-step explanation:

Lets find x-intercept:

for y substitute 0

4x+0=12x-1

subtract 4x both sides

0=8x-1

add 1 both sides

1=8x

divide 8 both sides

[tex]\frac{1}{8}[/tex]=x

lets find y-intercept:

for x substitute 0

4(0)+y=12(0)-1

multiply 4(0) and 12(0) which would equal 0 in this case, you dont have to write the 0s.

A. Conjecture
B. Guess
OC. Postulate
0 D. Theorem

Answers

Answer:

A. Conjecture

B. Guess

Steps of a proof cannot be explained using A. conjecture and B. guess.

What is Conjecture?

Conjectures in mathematics is a term which is given to the situation where something is guessed without any proof or basics.

This may be true, but are not proved up to this day.

Theorems are something which are already proved. This can be used in figuring out the proof of any problems.

Similarly, postulates are something which are the special cases of a certain proof. These can also be used to prove anything in mathemetics.

But guess and conjectures are not already proved statements. So these cannot be used.

Hence the options are Guess and Conjectures.

Suppose a 99% confidence interval for the mean weight of high school girls in pounds is (102.3, 106.5). If we had measured the weights of each of the girls in kilograms (2.2 pounds = 1 kilogram) then the confidence interval for the mean weight of high school girls in kilograms would have been

Answers

Answer:

The confidence interval for the mean weight of high school girls in kilograms would have been would have been (46.5, 48.41).

Step-by-step explanation:

To find the interval, we can just make the conversion of the values from pounds to kilograms.

Each kilogram has 2.2 pounds. So, to realize the conversion from pounds to kilograms, we divide by 2.2.

Confidence interval: (102.3 pounds, 106.5 pounds).

102.3 pounds = 102.3/2.2 = 46.5 kilograms

106.5 pounds = 106.5/2.2 = 48.41 kilograms

The confidence interval for the mean weight of high school girls in kilograms would have been would have been (46.5, 48.41).

What is the length, in centimeters (cm), of y?

Answers

Answer:

Step-by-step explanation:

Use Pythagorean Theorem for a right triangle.

a^2 + b^2 = c^2

3.6^2 + 4.8^2 = c^2

c = 6cm

The length of y (Hypotenuse) is 6 cm.

We have,

Perpendicular = 3.6 cm

Base = 4.8 cm

Hypotenuse = y

Using Pythagoras theorem

Hypotenuse² = Base² + Perpendicular²

So, y² = 4.8² + 3.6²

y²= 23.04+ 12.96

y²=

y= √36

y= 6 cm

Thus, the value of y (Hypotenuse) is 6 cm.

Step-by-step explanation:

From the question we are given the table

[tex]\begin\\\begin{tabular}{|l|l|l|l|l|} &&y \\x &0&1&2&3\\0 &0.13&0.1&0.07&0.03 \\1&0.12&0.16&0.08&0.04\\ 2&0.02&0.06&0.08&0.04\\ 3&0.01&0.02&0.02&0.02\end[/tex]

Generally the marginal probability mass function of X is mathematically given as
